Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76720, here are decompositions:
- 3 + 76717 = 76720
- 23 + 76697 = 76720
- 41 + 76679 = 76720
- 47 + 76673 = 76720
- 53 + 76667 = 76720
- 71 + 76649 = 76720
- 89 + 76631 = 76720
- 113 + 76607 = 76720
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.43.176.

- IPv4-mapped IPv6
- ::ffff:0.1.43.176
Unspecified address (0.0.0.0/8) — "this network" placeholder.
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
The digit sequence 76720 first appears in π at position 111,687 of the decimal expansion (the 111,687ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
